Long-Term Results of Anti-Protrusio Cage and Massive Allografts for the Management of Periprosthetic Acetabular Bone Loss

The use of customized cages in revision total hip arthroplasty for Paprosky type III acetabular bone defects

“…Although many approaches have been developed, such as revision with jumbo acetabular components, oblong cups, structural grafts, reinforcement rings, antiprotrusio cages, and cementless modular revision system, there are few reliable options [1][2][3][4]. Furthermore, despite greatly enhancing the surgeon's ability to reconstruct severely compromised acetabula, the recently developed porouscoated or ultraporous metal cups, shells, and augments do not fully recapitulate the lost bone [5,6].…”

Novel Use of a Trabecular Metal Augment in a Severe Acetabular Defect

“…[6][7][8] Current reconstruction methods present a number of challenges. Jumbo cups are frequently undersized to reconstruct these large defects.…”

Clinical evaluation and surgical options in acetabular reconstruction: A literature review

“…[17][18][19][20][21][22][23][24][25][26][27] Regis et al reported an 87% (49/56) survival rate at a mean follow-up of 11.7 years in type IIIA (32%) and IIIB (68%) hips using cages and structural allografts using radiographic evidence of bone ingrowth and remodeling as the primary endpoint. 28 The major disadvantage of cages includes high complication rates previously reported by multiple authors. 14,[29][30][31][32] There is a higher risk of neurovascular injury since large exposure of the ileum and ischium is needed to anchor the cage.…”
